Answer:
Empirical: OH
Molecular: 
Explanation:
First of all, we are going to use the formula: mass = no. moles x Molar Mass And rearrange it to find No. moles: No. moles = mass/Molar Mass
Let's start with Hydrogen:
The given mass is 0.44g, and hydrogen's molar mass is 1.01, therefore the number of moles is: 0.44/1.01 = 0.4356
Now we do the same for Oxygen:
Given mass = 6.92, Molar mass of Oxygen = 16.00, No. Moles = 6.92/16.00 = 0.4325
Now we identify the smaller one (Oxygen as 0.4325 < 0.4356) and we divide both values by that number:
0.4325/0.4325 = 1
0.4356/0.4325 = 1.01
We round both to the nearest 0.2 or 0.25 (depending on what you're taught), and we get: 1 and 1.
This means that the empirical formula has one of each: OH
Now to find the molecular formula we find the relative mass of OH and divide the given mass by that:
M(OH) = 16.00+1.01 = 17.01
34.00/17.01 = 2
We now multiply both by this number to get:

A cell spends the majority of its time in interphase because during this period the cell grows and synthesizes materials required during and after its division. During interphase, the cell duplicates its genetic material.
The cell cycle can be divided into a long interphase and a short mitotic (M) phase.
The interphase can in turn be divided into three phases: Growth 1 (G1) phase, Synthesis (S) phase and Growth 2 (G2) phase.
During the S phase, the cell duplicates its genetic material, which is sharply controlled by different cellular mechanisms (e.g., checkpoint mechanisms).
During G1 and G2 phases, the cell synthesizes all the proteins required during the M phase and after cell division.

2 and a half, the answer has to be that because its not long enough
No. However, energy is required for facilitated diffusion. Also without the membrane, the cell would collapse and wouldn't be able to function.
The answer is-Hydroelectric Hope this help
